Examples of Adding and Subtracting Mixed Numbers

When working with mixed numbers, it's important to understand how to add and subtract them. Here are two examples to illustrate these operations:

Example 1: Adding Mixed Numbers Let's say we want to add the mixed numbers 3 1/4 and 2 2/3.

First, we add the whole numbers: 3 + 2 = 5.

Then, we add the fractions: 1/4 + 2/3. To do this, we need to find a common denominator, which in this case is 12. So, we convert 1/4 to 3/12 and 2/3 to 8/12.

Now, we can add the fractions: 3/12 + 8/12 = 11/12.

Putting it all together, we get: 3 1/4 + 2 2/3 = 5 11/12.

Example 2: Subtracting Mixed Numbers Let's consider the subtraction of the mixed numbers 4 3/5 from 7 1/8.

First, we subtract the whole numbers: 7 - 4 = 3.

Then, we subtract the fractions: 1/8 - 3/5. To do this, we need to find a common denominator, which in this case is 40. So, we convert 1/8 to 5/40 and 3/5 to 24/40.

Now, we can subtract the fractions: 5/40 - 24/40 = -19/40.

Putting it all together, we get: 7 1/8 - 4 3/5 = 3 - 19/40.

These examples demonstrate how to add and subtract mixed numbers by combining the whole numbers and fractions separately.
